Power-One has introduced three 65W, single-output, AC/DC power supplies delivering 15, 24, and 48VDC; the SBLP65-1015G, SBLP65-1024G, and SBLP65-1048G. A quasi-resonant zero-voltage switching topology delivers efficiencies of 80 – 85% at full-power operation and at load conditions as low as 10%; providing significant energy savings in networking, commercial, and industrial applications.

Less than five CFM airflow is required to provide full-rated power and up to 60 watts is available with only convection cooling. These reduced cooling requirements facilitate greater overall-system layout flexibility as the SBLP65 does not have to be located directly adjacent to a system fan, or may completely eliminate the need for a dedicated power-supply cooling fan, especially in space-constrained 1-U “pizza-box” applications.

Additional features include: 75-watt peak power capability, 90-264VAC wide-range input, remote sense, compact 2 x 4 (51 x 102mm) footprint, low-profile 1-U compliant 1.3 (33mm) height, and six-substance RoHS compliance. These rugged products meet EN61000-4-2 level 4 (ESD), EN61000-4-3 (RF), EN61000-4-4 level 3 (Fast Transient/Burst), and EN61000-4-5 class 3 (Surge).

Regulatory agency approvals include UL60950-1/CSA 22.2 No. 60950-1 and TUV approval to EN60950-1. Onboard EMI filtering provides Class B compliance to FCC CFR Title 47, Part 15, Sub-Part B - Conducted; and EN55022/CISPR 22 Conducted Class B. These SBLP65's are competitively priced at $20 each in OEM quantities. Evaluation units are available from stock. Production quantities are typically available in 10 to 12 weeks.
